For data input you can also use a barcode reader which provides a
PS/2 connection. Older barcode reader may possibly have a too-high
power consumption, which could result in the cancellation of the sys-
tem test when the instrument is switched on. In such a case remove the
connected keyboard and switch on the instrument again.
